This invention relates to a tens carrying mechanism and is a division ofour application Serial No. 412,346, filed September 25, 1941.

The present invention is embodied in a machine of the general typedisclosed in Letters Patent of the United States Nos. 1,619,796;1,761,542; and 1,916,535, issued, respectively, March 1, 1927; June 3,1930; and July 4, 1933, to Bernis M. Shipley; No. 2,141,332, issuedDecember 27, 1938, to Charles H. Arnold; and No. 2,176,561, issuedOctober 17, 1939, to Everett H. Placke.

The present invention is directed to a tens transfer mechanism adaptedto a machine which includes four totalizer lines, each line consistingof a maximum of ten sets of interspersed totalizer wheels.

The principal object of the invention is to provide a novel tenstransfer mechanism which is particularly adapted to a machine includinginterspersed totalizers.

Another object of the invention is the provision of improved transfermechanism for transferring tens digits from lower denominations tohigher denominations.

Another object of the invention is to provide novel means to shift'thetotalizers laterally, for the purpose of transferring from lower tohigher denomiational orders, without disturbing the previous selectionof any totalizers under con trol of a selecting differential mechanism.

A specific object of the invention is to provide a tens transfermechanism wherein the tens transfer elements are adjacent the amountentering actuators for interspersed totalizers; means for laterallyshifting the row of interspersed totalizers for selecting a totalizerfor actuation; and other means to shift the selected totalizer linelaterally into alinement with the tens transfer segments after theamount has been entered, preparatory to receiving the tens transferentries.

, With these and incidental objects in view, the invention includescertain novel features of construction and combinations of parts, theessential elements of which are set forth in appended claims and apreferred form or embodiment of which is hereinafter described withreference to the drawings which accompany and form a part of thisspecification.

GENERAL DESCRIPTION The keyboard of the machine embodying the instantinvention comprises a plurality of rows of amount keys which in addingoperations control the positioning of corresponding amount differentialmechanisms, said differential mechanisms in turn being arranged totransmit the values of the depressed amount keys to the printingmechanism and to the wheels of the selected totalizer. In sub-total ortotal recording operations, the amount differential mechanisms, whichinclude an amount actuator for each denominational order, are positionedby the ling the lateral shifting of the corresponding totalizerframeworks to aline the various sets of. totali'zer wheels with theamount actuators. The

four rows of transaction keys likewise control the lowest order. Afterthe selected totalizer wheels are engaged with the transfer segments,said segments are released to the driving action of their springs, tocause the tripped segments to advance the wheels of the next higherorder one digit,'to 'eifect a tens transfer. v v

The selected set of 'totalizer wheels remains in alinernent with thetransfer segments at the end of the machine operation and are shiftedback into alinement with the amount actuators at the beginning'o-f thesucceeding operation, at which time all the previously tripped transfersegments positioning of four corresponding add selecting,

disks, which, in cooperation with their respective feeler mechanisms,control the radial shifting movement of the framework for thecorresponding totalizer lines to cause the selected set of totalizerwheels on the selected totalizergline to be engaged with and disengagedfrom the amount actuators.

The amount differential mechanisms are driven by a main. cam shaft,which in adding operations makes one revolution and in sub-totalrecording or reading operationsand in total recording or resettingoperations makes two such revolutions. Adding operations, which requireone revolution of the main cam shaft, are commonlyreferred to asone-cycle operations, and sub-total and total recording operations,which require two revolutionsof the cam shaft, are commonlyreferred toas two-cycle operations.

In adding operations, initial movement of the differential mechanisms,under influence of the cam shaft, causes said mechanisms to bepositioned under control of the depressed amount keys, and, duringthispositioning, the framework of the selected totalizer line is shiftedlaterally,

' under influence of the depressed transaction keys,

to aline the selected set of totalizer wheels thereon with the amountactuators. After the selected set of totalizer wheels has been alinedwith the amount actuators, the corresponding feeler mechanism, incooperation with the corresponding selecting disk, which has previouslybeen positioned .under influence of the depressed transaction key,

causes the totalizer engaging mechanism to' be connected to theshiftable' framework for the selected totalizer line. Operation ofthe'totalizer engaging mechanism causes the selected set of totalizerwheels to be engaged with the amount actuators after said actuators havebeen positioned by the amount keys, as explained above,

' and return movement of said actuators'under influence of the main camshaft, rotates the selected totalizer wheels in accordance with thevalues of said depressed amount keys to add in said wheels the amountset up on the keyboard.

A novel tens transfer mechanism, which functions in adding operations,is provided for transferring tens digits from lower to higherdenominations. In adding operations, when the wheels of the selectedtotalizer pass from 9 to while being rotated in an additive direction bthe amount actuators, a long tooth on said wheels trips the transfermechanism for the next higher order. After the amount actuators havecompleted their return movement, the'framework for the selectedtotalizer line receives an auxiliary lateral shifting movement to movethe selected set of totali'zer wheelsout of alinement with the amountactuators and into alinem'ent with a series of transfer segments whichare located adjacent to the corresponding amount actuators, there beingone such transfer segment in each denominational order "of each of thefour totalizer lines except the are restored to .un'tripped position.

DETAILED DESCRIPTION Amount Difierentz'als The amount, keys 56 (Fig. 1)control the positioning of corresponding amount differential or actuatormechanisms, and, inasmuch as this differential mechanism i substantiallyduplicated in each denominational order, it is believed that adescription of the mechanism of one such denomination'al order, as shownin Fig. 1, will be sufflcient for the purpose 'c-fthis specification.

The amount'keys M (Fig. l) of the denominational row here'shown, whichis representative of all the rowsof amount keys, are mounted in aframework I0?! supported rods Iill and 'I II] in turn supported by themain framework of the machine; Depression of any one of the amount keys54 rocks a zero stop pawl I82 counter-clockwise out of the path of aprojection N3 of an amount actuator Hi4 free. on ashaft I journaled inthe main frames 59, and moves the lower end of said depressed key intothe path of said projection I63. When no amount, key 55 is depressed,the zero stop pawl IiiZ, under influence of a spring Iil9, is retainedin'the path of the projection I63 and breaks the latch for this amountbank in zero position, as will be explained later.

The'actuator' I84 (Fig. 1) has therein an angular camming slot III,through which extends astud H2 in alatch II3 pivoted on a stud IMcarried by a latch arm II5 free on the shaft I195. The stud I12 alsoextends through an angular camming slot H6, which'isla-companion slot totheislot II, said slot .I I6 being in a differential balanceplate II'Ifree on the shaft W5. A footshapedextensio'nyof the latch II3 hasthereon a shoulder H3, which, in cooperation with a, similar shoulder ona .latch'drivingsegment I I9 free on the shaft I05, forms a drivingconnection between. said segment and the latch arm H5. A

,link' I20 operativelyconnect's the driving segment IIQto' anoperating'le'v'er I2! pivoted on a stud I22 in a partitioniplate I23 forthisparticular amount bank, there being such a partition plate for eachamount bank.

A boring in a downward extension'of the lever I2I freely'engagesa rod124, opposite ends of which are secured in similar arms I25 (only'theleft-hand arm b'eing shown here), said arms being pivoted on studs (notshown) similar to and 'known in the art, 'operatively connects the main2,380,450 cam shaft I30, to the operating motor, said motor beingarranged, to drive the shaft I30 one clockwise revolution in addingoperations and two such revolutions in reading and resetting operations.Revolution of the main cam shaft I30, by means of the cams I28 and I29,imparts an invariable oscillating movement to the arms I25, the lever.I2I, and the latch-operating segment I I9, first clockwise and thencounter-clockwise.

Initial movement clockwise of the segment I I9, by means of the shoulderthereon in cooperation with the shoulder II8 on the latch II3, carriessaid latch and the latch arm II clockwise in unison therewith. The latchI I3, by means of the stud I I2 in cooperation with the slots I II and II6,

carries the actuator I04 and the balance plate II1 clockwise in unisontherewith. In this case, a spring I61 and the downward inertia of thebalance plate II1 causes the slot H6, in cooperation with the stud I I2,to retain the latch in engagement with the segment H9 and therebyovercomes any tendency of the slot III in the actuator I04 to cam saidlatch II3 out of engagement with the shoulder on the operating segmentH9. The actuator I04 moves in unison with the segment II9 until theprojection I03 engages the lower end of the stem of the depressed key54, which obstructs, further clockwise movement of said actuator I04.Stopping of the actuator I04 causes the cam slot III, in cooperationwith the stud II2, to cam the latch II3 counter-clockwise "to disengagethe shoulder II8 from the segment I I9 and simultaneously to engage anarcuate surface on the top of said latch with the corresponding one of aseries of alining notches I32 in a curved alining bar I33 secured to thepartition plate I23 for this particular amount bank, said plate I23being supported by the shaft I05 and the rods I34, I35, and I35, in turnsupported by the main framework of the machine. {is the segment II9continues its clockwise movement without interruption, an arcuatesurface thereon passes in the path of the foot-shaped extension of thelatch II3 to lock said latch, the arm H5, and the actuator I04 in setpositions.

The actuator I04 has, on the periphery thereof, a plurality of gearteeth I31 arranged to cooperate with the different sets of totalizerwheels I38 to I4I inclusive, carried respectively by the Nos. 1, 2, 3,and 4 totalizer lines.

In adding operations, after the actuator I04 has been positioned, asexplained above, the selected totalizer line is shifted radially toengage the corresponding one of the selected set of totalizer wheelsthereon with the teeth I31 of the actuator I04. After the correspondingone of the selected set of totalizer wheels has ben engaged with theactuator I04, return movement counterclockwise of the operating segmentI I9 moves the arcuate surface on said segment beyond the footshapedextension of the latch I I3 and simultaneously causes a stud I42 carriedthereby to engage a raised surface on the latch arm II5 to rearm II5causes the alining notch I32, in cooperation with the arcuate surface onthe latch I I3 and the spring I61, to reengage the shoulder II8 on saidlatch I I3 with the corresponding shoulder on the operating segment I I9. During its return movement counter-clockwise, the actuator I 04,rotates the wheel I38 of the selected totalizer in -3 an additivedirection, in accordance with the value of the depressed amount key 54,to add said value into said wheel.

An aliner I43 (Fig. 2), in cooperation with the teeth I31, retains theactuator I04 in set position in all types of operations. Obviously thealiner I43 is disengaged while the actuator I04 is being positioned.

The differential movement of the actuator I04 is transmitted to theindicator mechanism by the well-known minimum movement mechanismincluding beam I45, link I41, and segment I48. The link I41 alsotransmits the differential setting movement of the actuator to typecarriers I58, through segment I50, link I52, segment I53, and theWell-known internal-external gear mechanism I55, the latter being fullydisclosed in United States Patent No. 1,693,279, issued November 27,1928, to Walter J. Kreider.

Transfer mechanism A tens transfer mechanism is provided fortransferring tens digits from lower to higher denominations. Thetransfer mechanism for each totalizer line comprises a transfer segmentand its associated tripping mechanism for each denominational order,except the lowest order, and, when a totalizer wheel passes from 9 to 0While traveling in an additive direction, the long tooth thereon tripsthe transfer mechanism for the next higher order. The transfer segmentsare located adjacent to and parallel with the corresponding amountactuators; therefore, after the amount actuators have completed theirreturn movements, to enter the value of the amount set up on the amountkeys in the selected totalizer wheels, it is necessary to shift theselected totalizer line or lines a slight distance laterally to alinesaid wheels with the corresponding transfer segments. Immediatelythereafter, the previously tripped transfer segments function to add onein the totalizer wheels of the nextv higher orders.

During the auxiliary shifting of the totalizer 'line to move theselected totalizer wheels into alinement with the transfer segments,said line; is partially disengaged to insure that said wheels; do notstumble on the transfer segments and to insure that adjacent wheels donot stumble on the teeth of the actuators. The selected totalizer wheelsremain in engagement with the transfer segments at the end of machineoperation and are disengaged therefrom immediately at the beginning ofthe succeeding operation, after which the totalizer line is restoredlaterally to aline the wheels thereof with the amount actuators.

Inasmuch as the transfer mechanisms for the different denominationalorders and for the different lines of totalizers are identical, it isbelieved that a description of the transfer mechanism for thedenominational order of the No. l totalizer line shown in Fig, 1, willsuffice.

The transfer mechanism for the denominational order of the No. 1totalizer line, shown in Fig. 1, comprises a transfer segment I10 (Fig.2) pivoted on a stud I1I in a plate I12 supported by the rods I34, I35,and I36. Aspring I13 urges the segment I10 counter-clockwise to normallymaintain a camming surface I14 thereon in engagement with a stud I15 ina transfer operating arm I16 free on a stud I11 in the plate I12. Aspring I10 urges the arm I16 clockwise to normally maintain a bent-overear I19 thereon in contact with a retaining tooth I on a trans fer tripyoke 'I8I- free on a stud I82 inthe plate I12 for the order here shown.

When the selected No. 1 totalizerwheel I30, in the next lower order to.the order shown in Figs. 1 and 2, passesthroughzero, along tooth I83thereon engages a bent-over extension I84 on the yoke I8I and rocks.said yoke counter.- clockwise to disengage the tooth I80 from theear-I19 to release the arm I16 to the action of thespring I18, whichrockssaid .arm a. slight distance clockwiseuntil the ear I10passes-beyond the tooth I80 and untila, dependingfinger I85 of said armI10 contacts .a stud I80, which at this time is in the position hereshown in dot-anddash lines The stud I80 is secured in a restoring diskI81 fast on the shaft I05, there being such a disk for eachdenominational order, with the exception of the lowest order. Also faston the shaft I (Fig.2). is a crank I 00 carrying a stud I89 embraced bya. slot. in acam lever I90 free on a stationary stud I9I. Angularlydisposed arms of the lever'I90 carry, respectively, rollers I92 and I93,which cooperate respectively with the peripheries of companion platecams I90 and I95 secured on the main cam shaft IS. The timing of thecams I04 and I95 is such that initial movment of said cams, through thelever I90,- rocks the disk I81 clockwise, causing the-stud I00, incooperation with thedepending finger I85, to restore the operating armI16 counter-clockwise against the action of its spring H0 until the earI19 passes beyond the tooth I80. Continued rotation of the cams I94 andI95 returns the disk I81 and the stud I86 a slight distancecounter-clockwise to permit the ear I19 to engage the tooth I80 to latchthe transfer mechanism in untripped position, and to position thestudI80 a slight distance away from the finger I85, as shown in dotand-dashlines in 2. Restoring movement counter-clockwise of the operating armI16 causes the stud I15, in cooperation with the camming surface 115, torestore the tripping segment I10 clockwise against the action of thespring I13.- I

It should be noted that the restoring of the transfer mechanism takesplace during initial movement of the amount actuators I04 and prior tothe time the selected totalizerwheels-are engaged therewith. Returnmovement of the amount actuator for the next lower order wheel I38 (Fig.2) rotates said wheel in an additive or clockwise direction; causing thelong tooth I83 thereon to engage the extension I84 to trip, the yokeI01, in the mannerexplained above. -After the amount actuator hascompleted its return movement, the-transfer shift is impartedto the No.1 totalizer line to move the wheels I of the selected totalizer intoalinement with the transfersegments' I10, and immediately thereafter thecams I94 and I95 return the disk I01 counter-clockwise to the positionshown here. The operating arm I10 moves clockwise in unison with thedisk I81, causing the stud I15, in cooperation with the camming surfaceI14, to permit the spring I13 to rock the segment counterclockwise toadvance the totalizer wheel I38, for the order here shown, one digit toeffect a tens transfer.

The mechanism for imparting auxiliary or transfer shifting movement tothe totalizer line will be explained later herein in connection with thetotalizer selecting and engaging mechanism.

In reading and resetting operations, the wheel I38 (Fig. 2) is reverselyrotated by the amount actuator I04 until the long tooth" I83 thereoncomes into contact with the extension I81 to locate said wheel in zeroposition and t position the actuator and the recording mechanism inaccordance therewith.

Transactionlc'eys and differential mechanism therefor The differentialmechanism for each. of the four rowsoftransactionkeys is simi1ar:inevery respect to the amountdifferential mechanism shown in Fig, 1 andexplained above, and, as the transaction differentiahmechanism issubstantially duplicated for each row of transaction keys,-. itrisbelieved thata description of ,the differential mechanism. for the firstrow of transaction keys, shown in Fig. 3, will suflicefor all.

The transaction keys 55 for the first transaction bank are mountedxinakey frame I supported by the rods IOI and III) in, exactly the samemanner as the amount key banks. Depression of. any one of thetransaction keys 55.ro.cks a zero stop pawl I99 counter-clockwise out ofthe path of a projection 200 ,of an actuator .20I free on the shaft I05,said actuator 20I being operatively connected to abalance plate 202 bymeans of angular slot in said actuator and said plate, in cooperationwith. a stud in a latch203 pivotally mounted on a latcharm 204 free onthe shaft I05. The latch 203 cooperatesswith a shoulder on adifferential operating segment 205 free on the shaft I05 and connectedby a'link 200 to an operating lever 201 .free on a stationary stud 298.The cam lever- 201 carries rollers 29 and 2E0, which cooperate,respectively, with the peripheries of companion plate cams 2 II and 2I2secured on the main camshaft130. The cams 2H and H2 function torocktheactuator 20I first clockwise and back to normal position during eachrevolution of said main shaft I30. The parts of thetransacticndifierential described briefiy above are similar to andfunction exactly like similarparts of the amount actuator shown in Fig.l and described earlier herein.

Initial movement clockwise of the lever 201,

through the segment 205 and the latch 203, carries the actuator ZOIclockwise in unison therewith until the projection 200 contacts the stemof the depressed transaction key, which positions said actuatoraccording to the value of said depressed transaction key. Thisdisengages the latch 203 from the segment 205 in exactly the same manneras described for the amount bank, thus permitting said s'egmentand thelever 201 to complete their initial movements clockwise independentlythereof. When the lever 201nears the terminus of its initial movementclockwise, a roller 213 carried thereby engages anarcuate surface on abeam 254 pivoted on thearm 204, to position said beam in accordance withthe depressed transaction key. -The rearward end of the beam 214 isbifurcated to embrace a stud 22-5 in a 11m; 21s, the upper end of whichlink is pivotally connected to a gear sector 2l1 secured to one, of aplurality of nested tubes 2 I8' freeon the. shaft M9. The. lower end ofthe link '21s is pivotally connected to asegment 2I9 free on the shaftIEI, and connected by a sleeve 220 to a crank 221. The crank 22I '(Figsld and 4) is connected by a link 222 to a segment 223 free on the shaftI05, said segment meshing with a gear 220 secured on a short shaft 225journaled in plates 225 and 221 supported by the rods I34, 135,8.1101136(Fig. 1).

Also secured on the, shaft,225-(Figs. 3 a'nd 4) is a disk carrying threestuds 220*(onlytv'vo right-hand end of the No. 1

being shown), which freely engage corresponding borings in theleft-handface of a'drum cam 230 free on the shaft 225. The cam 230 has a helicalcam groove 23I, which cooperates with a roller 232 secured in a slide233 shiftably mounted on the top surface of a yoke 234 by means of studsin said slide in cooperation with horizontal slots in said yoke, saidroller 232 arranged to extend through one of said horizontal slots. Theyoke 234 is free on the shaft 225, but is held against rotary movementby a roller 235 carried thereby, in cooperation with a horizontal slotin a bracket 236 secured to the plate 226, and by means of a verticalslot in the left-hand extension thereof, in cooperation with a stud 231in the Plate 221. An annular groov 238 (Fig. 4) in a reduced portion ofthe drum cam 230, in cooperation with a slotted bracket 239 secured tothe yoke 234, maintains said drum cam and said yoke in fixed lateralrelationship to each other.

An upturned portion of the-slide 233 (Figs. 3 and 4) has therein a slot240, which engages an annular groove MI in a hub portion of a totalizerframe side member 242, said hub portion having therein a boring whichfreely engages a shaft 243 which is arranged to be shifted radially in amanner presently to be described, to engage the selected set oftotalizer wheels with the amount actuators. The side member 242 supportsthe totalizer line or rod, while a similar side member 258 (Fig. 1),also slidably mounted on the shaft 243, supports the left-hand end ofsaid No. 1 totalizer line, said side members, together with the No. 1totalizer line and the shaft'243, forming a shiftable framework forengaging and disengaging the No. .1 totalizer wheels with and from theamount actu ators. The lower ends of the side members 242 and 258 havetherein similar slots which engage similar tooth-shaped blocks 244I(Fig. 4) carried by the plates I23, said blocks being the shape of andin alinement with the teeth in the actu ators I04 (Fig.1).

The roller 235 (Figs. 4 and 6) extends into a cam slot 244 in one offour camming extensions on a transfer. shift cam 245 free on the shaftI05. An extension 246 of the cam otally connected thereto the upper endof a link 241 having a stud 249 in the lower end, which normally engagesa slot in an'arm 248 fixedly connected, by a hub free on a stud 250 inthe plate 226, to a cam arm 25I. The cam arm 25I carries rollers 252 and253, which cooperate respectively with the peripheries of companionplate cams 254 and 255 secured on the main cam shaft I30.

The timing of the cams 254 and 255 is such that the arms 25I and 248 andthe cam 245 (Figs 5 and 6) are shifted clockwise prior to initialmovement of the amount actuators I04. Clockwise movement of the cam 245,by means of the slot 244 in cooperation the yoke 234 toward the left, asviewed in Fig. 4, which movement is transmitted by the bracket 239 tothe drum cam 230 andthence by the cam groove 23I and the roller 232 tothe slide 233. This shifts the member 242and the No. 1 totalizerframework a slight distance toward the left to move theselectedtotalizer wheels out of alinement with the transfer segments Iand into alinement with the amount actuators I 04 (see also Figs. 1 and2).

After the selected set of wheels on the No. 1

totalizerhas been shifted out of alinement with 245 has pivwith theroller 235, shifts the transfer segments, as explained above, the roller2I3 (Fig. 3) engages the beam 2I4 to position said beam in accordancewith the depressed transaction key, and this positioning is transmittedby the link 2I6 to the sector 2I1, the segment 2I9, and the crank 22I.The crank 22I, by means of the link 222, rocks the gear segment 223 fromzero position, as here shown, in a clockwise direction to a positioncorresponding to the depressed transaction key. Clockwise movement ofthe segment 223 (Fig. 3) rotates the gear 224, the shaft 225, and thedrum cam 230 counterclockwise, causing the cam groove 23I (Fig. 4) insaid drum cam, in cooperation with the roller 232, to shift the slide233 and the totalizer framework, comprising the members 242 and 258 andthe No. 1 totalizer line, toward the left, as here viewed, to aline theset of totalizer wheels I38 corresponding to the depressed transactionkey 55 with the amount actuators I04.

In adding operations, after the selected set of totalizer wheels hasthus been alined with the amount actuators, radial shifting movement isimparted to the shaft 243 (Figs; 1 and 3), as will be presentingexplained, to engage the selected totalizer wheels with the amountactuators I04, after said actuators have been positioned under influenceof the depressed amount keys. Return movement counter-clockwise of saidactuators rotates said wheels in an additive direction to enter theamount therein, and, after said actuators have completed their returnmovements, the totalizer wheels are slightly disengaged from theactuators, and the cams 254 and '255 (Fig. 6) function to shift the No.1 totalizer a slight distance to the right to move the selected set ofwheels thereon into alinement-with the transfer segments I10; Afterthis, the Norl'totalizer line is returned to full engaged position andthe tripp d transfer segments I10 (Fig. 2) then function, underinfluence of their cams I94 and I95, to effect the transfer of tensdigits from lower to higher, denominations, in the manner explainedearlier herein.

At the endof a machine operation, the selected set of totalizer wheelsremains in alinement with the transfer segments I10 and is returnedintoalinement with the amount actuators I04 at the beginning of thesucceeding operation.

Totalieer engaging mechanism In machines of the type to which thepresent invention is shown applied, a selecting means un der control ofthe transaction banks of keys is provided for selecting the line oftotalizers to be engaged with the-amount differentials I04 for receivingentries. Since this selecting means forms no part of the presentinvention, it is not disclosed herein. thereof, reference may be had tothe parent case, referred to hereinbefore. For the purpose ofunderstanding the present invention, it is only 'nec-' essary to knowthat, when a totalizer on a selected totalizer line is to be engagedwith the amount actuators, a stud 3I0 (Fig. 5) is rocked into engagementwith a notch 348. at the proper time, and when said notch is alined withthe stud 3 I 0.-

The stud 3I0 is carried on a link 3 pivotally connected to the end of alever 3 I2 free on a stud 3I3 in the frame 5|. A link 3| 4 pivotallyconnects the lever 3| 2 to the end of a lever 3I5 secured on the shaft243, said lever carrying a roller 3 I 6, which engages a camming slot3I1 in a totalizer engaging plate 3 I8 secured to the frame For acomplete disclosure 5!.

Operation The novel tens transfer" mechanismoperates as followsz Thetransaction keys 55 control the selection of-a 't'otalizer line by wellk'now'n inea'n's described in the parent'application and in ithepaten'ts referred'to herein: After a'line has beenselected, a utotalizeron the line is selected by the depressed control key 55, which, throughthe differential mechanism controlled thereby," rotates segment 223 anddrum" cam 23!] to shift the desired-totalizer into alinement with theamount actuators I04. Thereafter, the engaging mechanism shown in Fig!5' engages the' s'elected totalizer- -with the actuators I04,sothatamourits set-on the keyboard can" be entered in the totalizer.

(Fig. 2'). After the ainount has been entereddntothetotalize'rg the-totaliz'er is partially disengaged-from the rackslll4 'by cams 338-339 I (Fig.5) and the "mechanis'rn 'op'erated thereby;Thereafter, 'the-totalizer line-is shifted by earn 254-255 (Fig.6)"-t'o' aline the totalizer. int0= which the'amountswereentered by theamount differential, with the transfer segments I10. "After thetotaliz'er wheel'sareengagedWith the segments l-ll'hthe-stud's' ltfi arewithdrawnto their original position by cams ISM-495 (Fig. 2) to releasethe tripped arms I16, which in turn releases the associated transfersegments I to enter the tens carries in the proper totalizer elements.Thereafter, the machine comes to rest.

Near the beginning of the next machine oper ation, the cams 338339disengage the totalizer from the actuators, and the cams I94--l 95thereafter restore the trippedtransfer segments I!!! by moving themember I81 and the studs I86 clockwise slightly beyond the dot-and-dashposition shown in Fig. 2. This movement of the studs I86 past suchposition rocks the members I16 counter-clockwise until the trip members|8l again latch the members H6 in the positions shown. During suchcounter-clockwise movement of the members H6, the studs I thereon movethe transfer segments I10 back to their normal positions.
